CONDENSER.

- Myyinventiomrelates to condensers such 7 as employed for condensingthe. exhaust steam from steam engines or turbines, or for similarpurposes.

in accordance with my invention, within a single condenser unit thecondensable fluid, as steam, passes around tubes through which coolingmedium passes, and passes through tubes around whlch the cooling mediumpasses, the condensable fluid. preferably taking the paths described inthe order named. l

My invention resides in condenser structure of the characterhereinatterdescribed and claimed.

For an example of one of the various forms an; invention may: take,reference is to be had to the accompanying drawing, in which: I

Fig. l is a longitudinal sectional view through structure embodying myinvention. Fig. 2 is across sectional view on the line 22 of Fig. l.

Fig. 3 is'a cross sectional view taken on the line 3-3 of Fig. l.

Fig. 4iis a cross sectional view taken on the line 4 4 of Fig. l.

Referring to the drawing, O is the condenser sh'ell or body having onits ends the tube sheets S and 8 held between flanges on the shell G andthe end boxes A and lid.

Lxtending through the tube sheets is a group D of condenser tubes ofbrass or other suitable material, around andbetween which llows theiluid to be condensed, as steam, en= tering the shell C at E, thecondensate collecting}; in the bottom oi the shell U and passing; outthrough the outlet F to the hot well or any other suitable destination,the lower side or": the group ll) being suitably spaced above the bottomout the shell C. "l this space between the lower side nrough the group Dand the bottom ot the shell til, when are structure is positioned as indicated in l, and thence through passage at the bottom the tube sheettil flows the uncondensed steam and any un condensable fluid in mixturetherewith, air, into the chamber H beneath the parti= ticn It in the endbox A. The chamber H, as indicated in Fig. 3, extends to one side andupwardly in the box A between theouter wall of the box A and theextensions l? and l of the aforesaid partition l fjcm- 1921. serial No.485,208.

niunicating with this lateral portion of the chamber H are the condensertubes of a group J extending through the tube sheets S and Si within theshell 0, and between it and the partition plate or wall J extendinglongitudinally of the shell 0 between the same and between the tubesheets S and S the tubes of the group J discharginginto the chamber 1Kin the end box B, Figs. 1 and 4, such chamber being form'edbe tween theshell (3 and the partition havin the section or portion L, corres ondingwit 1 partition ii in box A, the section L corre- .ponding with thepartition I in thebox A, tie section L corresponding with the section lin the box A, and the sections L and L The mixture of steam and airdischarged trom the tubes J into the chamber lit passes through saidchamber from left toward the right, Fig. 4, and enters the condensertubes of the group M extending between the tube sheets S and S anddisposed within the shell (l between the shell and the inclined wall orpartition N substantially in register with the section L or" thepartition in the box B. The tubes of the group M deliver into thechamber Q, Fi 3, disposed between the outer wall of tie chamcr A and aartition P, coincidirn with partition N. ubstantially nothing but airreaches the chamber U, and this is discharged or drawn oil b suitablepump, ejector or the like throng the air outlet Q,

The cooling water enters at and is de livered divided streams throughthe passages lt and into the chambers wit? the shell C containinarespectively, tube c n In oroups M and J, The cooling we s r 0 accordingj flows arounuthe tubes groups at d M, o e

thereafter through the openings l in the tube heet 6 into the chamberthe box 1; above partition ll ich chamber communicate tubes of he groupthe cooling water tlowing through the tubes D into the cl her in the boxA above the partitions a 1 l P, the water then through the water outletThe incoming steam theretore cornea into contact with tubes of the groupthrough which cooling water is hoping, such condensa e as has beentermed passing;

through the condensate outlet F; the uncondensed remainder then passesinto the chamber H of the box A and thence through the tubes of thegroup J to the chamber K in the box B, and thence through the tubes ofthe group M into the chamber 0 in box A, and the air passes otlthroughthe outlet Q.

The cooling water passes in divided streams first around the tubes ofthe groups J and, M, and thence through the tubes of the group D. 1

The water resulting from condensation of the steam passing through thetubes or" groups J and M is drawn oil in any suitable manner, as fromchambers K and U, respectively, as through the draw-off connections Yand Z4, respectively.

By an arrangement of the character above described, a greater amount ofsteam, other things being substantially the same, may be effectuallycondensed with a given amount of cooling water with a smaller amount ofheat transfer surface, that is, with fewer condenser tubes or shortercondenser tubes, or in general, with less tube surface, Ur with a giventube surface and given cooling water conditions, greater amounts ofsteam may be condensed,

ti hile have described a form of my apparatus wherein the steam firstflows around tubes through which cooling Water is passed, and thenthrough tubes around which cooling water passes, it will be understoodthat the reverse arrangement may be employed.

As shown by Fig. 2, the group of tubes is disposed between the shell (3and the downwardly inclined and-convergent partii tions 5 and N, betweenwhich latter the shell are disposed the other tube groups. thisarrangement, the steam passing aro ind the tubes of the group D isprogre" siv 1y condensed and thereby diminished amount, and with thepath diminishing cross section as enforce by the converg, partitions dand li the velocity of the steam remains substantially constant. In addition, the condensate produced around those tubes vertically above thepartitions d N collects upon those partitions and descends along them tothe bottom of the shell, By this arrangement, there are procured theadvantages of the so-called a -shaped surface condenser, and the spacebetween the partitions and the shell is usefully employed for the tubesof final condensers or coolers ld hat I claim is:

A. condens unit comprising at least three groups of tubes, the firstgroup com" prising the greatest number of tubes, and the other groupscomprising lesser numbers tubes, means for passing the fluid to be usedfirst around the tubes of said group and thence through tubes of saidother groups in succession, and for passing cooling water first aroundthe tubes of said other groups simultaneously and then through the tubesof said first group.
